 var time;
        window.onload = Monitor = function() {
            try {
                var dte = new Date();
                var url = "AppGroup.ashx";
                $.ajax({

                    method: 'GET',
                    dataType: 'html',
                    success: function(data) {
                        $("#lastime").html("最後一次更新時間:" + dte.toLocaleString());
                        if (data) {
                            $("#div_app").html(data);
                        }
                    }
                });
                if (time != null) {

                }
                time = setTimeout('Monitor()', 60000); //60 sec
            }
            catch (ex) {
